Important:
| • | If replacing a theft deterrent module with an GM Service Parts Operation (SPO) replacement part, the theft deterrent module will learn keys immediately. However, the existing Powertrain Control Module (PCM) must learn the new fuel continue password when the theft deterrent module is replaced. |
| • | If replacing a PCM with a GM Service Parts Operation (SPO) replacement part, after programming, these modules will learn the incoming fuel continue password immediately upon receipt of a password message. Once a password message is received, and a password is learned, a learn procedure must be performed to change this password again. A PCM which has been previously installed in another vehicle will have learned the other vehicles' fuel continue password and will require a learn procedure after programming to learn the current vehicle's password. |
| • | When performing the 10-minute or the 30-minute re-learn procedures, all previously learned keys will be erased from the theft deterrent module's memory. |
| • | Additional keys may be learned immediately after the 10-minute or 30-minute re-learn procedure by inserting the additional key to be learned and turning the ignition switch to RUN within 10 seconds of removing the previously learned key. |
| • | When performing the 10-minute or the 30-minute re-learn procedures, use only a master key (black) during the procedure. If a valet key (gray) is learned first, the theft deterrent module will not allow additional keys to be learned. |
10-Minute Re-Learn Procedure
Use this procedure after replacing the following components:
| • | The theft deterrent module |
| • | The Powertrain Control Module (PCM) if necessary , see Important above |
Tools Required
| • | Techline Terminal with current Service Programing System (SPS) software |
- Connect the Tech 2 scan tool to the vehicle's Data Link Connector (DLC).
- Select Request Information under Service Programing.
- Disconnect the Tech 2 from the vehicle and connect it to a Techline Terminal.
- On the Techline Terminal, select Theft Module Re-Learn under Service Programming.
- Disconnect the Tech 2 from the Techline Terminal and re-connect it to the vehicle's DLC.
- Turn the ignition switch to RUN, with the engine OFF, using a master PASSKey®III key (black).
- Select VTD Re-Learn under Service Programming.
- At this point the Tech 2 must remain connected to the DLC for the duration of the 10-minute re-learn period.
- Observe the SECURITY indicator. After approximately 10 minutes the SECURITY indicator will turn off. The vehicle is now ready to re-learn the key information and/or passwords on the next ignition switch cycle from OFF/LOCK to RUN.
- Turn the ignition switch to OFF/LOCK and wait 5 seconds.
- Start the vehicle. The scan tool has now learned the key and password information.
- With the scan tool, clear any DTCs
30-Minute Re-Learn Procedure
Use this procedure after replacing the following components:
| • | The theft deterrent module |
| • | The Powertrain Control Module (PCM) if necessary, see important above. |
- Turn the ignition switch to RUN, with the engine OFF using a master PASSKey®III Key (Black).
- Observe the SECURITY indicator. After approximately 10 minutes the indicator will turn off.
- Turn the ignition switch to LOCK, and wait 5 seconds.
- Repeat steps 1 through 3 two more times for a total of 3 cycles or 30 minutes.
Important: The vehicle learns the key information and/or passwords on the ignition switch transition from OFF/LOCK to RUN. You must turn the ignition switch OFF/LOCK before attempting to start the vehicle.
- Start the vehicle. The vehicle has now learned the key and password information.
- With a scan tool, clear any DTCs.
Quick Learn Procedure - Keys Only
Important:
| • | As many as 10 additional master keys (black) or valet keys (gray) may be added using this procedure when there is an available learned master key (black). |
| • | This procedure adds keys only, it does not erase previously learned keys. |
| • | The keys to be learned must duplicate the mechanical cut of the current key. |
| • | If more than one valet key (gray) is to be learned, each must be immediately preceded by a learned master key (black). |
- With a previously learned master key (black), turn the ignition switch to RUN, with the engine OFF.
- Remove the key from ignition key cylinder.
- Within 10 seconds, insert the key to be learned (either black or gray) and turn the ignition switch to RUN, with the engine OFF. The vehicle has now learned the new key.
